Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622894, here are decompositions:

13 + 31622881 = 31622894
31 + 31622863 = 31622894
151 + 31622743 = 31622894
181 + 31622713 = 31622894
211 + 31622683 = 31622894
223 + 31622671 = 31622894
421 + 31622473 = 31622894
547 + 31622347 = 31622894

Showing the first eight; more decompositions exist.
